The range operator doesn't work as you want in a regex character
class, and neither does the '|'.
I would do it like this:
#! perl
No I don't see why I need (). (but I do see an opportunity to learn
something...). The kludge I posted does work (with the sample data in the
original post). Why would () be required? If I understood the post
correctly the task did not require capturing any numbers.

Why not

Dave,
One possiblity:
use strict;
open(IN, "lfile.txt"); # ho;d the line from the example in the orig post
my $p1 = join('|', (512..520));
my $p2 = join('|', (528..568));
my $p3 = join('|', (576..578));
my $p4 = join('|', (592..600));
my $p5 = join('|', (608..622));
my $p6 = join('|', (624..6
oops...forgot parens around the \d+...

Unfortunately, the range operator doesn't work in a regex...though it would
be nice if it did (of course I could be wrong)... I would try something
like:
while( ) {
while( /,\d+,/g ) {
if( in_range( $1 ) ) {
# do whatever
last; #get out of the while loop
}
}
}
The fi
I don't think you can "or" in the middle of a character class. I think that
if you wanted to use that approach, you should have a separate character
class for each "or".
